To reduce the size and lower energy consumption are very important for the portable X-ray detector, it is visible that the nanodetector based on nanotechnology will be the future trend. In this paper, the single-crystalline Zn0.75Cd0.25Te nanoribbons are synthesized by a two-step process, and the X-ray detectors from individual nanoribbon are fabricated. The X-ray detecting performances are carried out by using three kinds of X-ray source with different energy of 8.857 KeV, 9.659 KeV and 11.564 KeV, respectively. The nanodetectors exhibit a high sensitivity, fast response speed, which are attributed to the high-aspect ratio, nearly perfect single-crystalline quality and the reduction of recombination barrier in the ribbon. The remarkable X-ray responsivity imply that the Zn0.75Cd0.25Te nanoribbons is a very attractive candidate for application in X-ray nanodetector at room temperature.
